WebbThe minimum size of a black hole that can form, through the only known mechanism that we know (stellar collapse) is about three solar masses or a little less. The minimum size of a black hole that can exist, without violating the laws of physics that we know, is the Planck mass, which is about 0.02 milligrams. [55] [56] [57] As of 2024, the nearest known body thought to be a black hole is around 1,500 light-years (460 parsecs) away. Though only a couple dozen black holes have been found so far in the Milky Way, there are thought to be hundreds of millions, most of which are solitary and do not cause emission of radiation. [58] Visa mer A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon. The theory of general relativity predicts that a sufficiently compact Visa mer The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent physical properties: mass, electric charge, and … Visa mer By nature, black holes do not themselves emit any electromagnetic radiation other than the hypothetical Hawking radiation, so astrophysicists … Visa mer Entropy and thermodynamics In 1971, Hawking showed under general conditions that the total area of the event horizons of any collection of classical black holes can never decrease, even if they collide and merge. This result, now known as the Visa mer The idea of a body so big that even light could not escape was briefly proposed by English astronomical pioneer and clergyman John Michell in a letter published in … Visa mer Given the bizarre character of black holes, it was long questioned whether such objects could actually exist in nature or whether they were merely pathological solutions to Einstein's equations. Einstein himself wrongly thought black holes would not form, because he … Visa mer The evidence for stellar black holes strongly relies on the existence of an upper limit for the mass of a neutron star.
